[Basic taxonomic groupings of the organisms participating in the formation of nest-burrow microbiocenoses].

The transition of arthropods, other invertebrates and microorganisms to the nest-burrow habitats was accompanied (if presented in a historical aspect) by an intensive speciation resulting in a rise of a peculiar life form, nidicoles. Now nidicoles are reported in such large taxons as Protophyta, Mycophyta, Protozoa, Nematoda and Arthropoda. The main part of nidicoles is represented by arthropods, members of the orders Acariformes, Parasitiformes, Blattoidea, Saltatoria, Mallophaga, Anoplura, Heteroptera, Coleoptera, Diptera and Siphonaptera.
